I found RealCalc back in 2013 and it immediately became a home screen staple. A few years later, I became a paying customer for RealCalc Plus, not because I needed more features, but because I felt that I should reward the developer for the use I was getting from the app. Now, in 2021, I still have it on my home screen and still use it as much now as I did then.

Like others I bought this at least 10 years ago and it's one I always come back to. I don't like the simple default calculators that come on phones. Even if I don't use the advanced features that much, it's nice to know they're there. The nostalgia feeling is great too. I'll often load up RealCalc on my phone instead of grabbing my real life calculator especially if the room is dark, that's no problem for RealCalc.

I LOVE this program. Laid out very similar to what I used in school for years. I'm constantly reaching for it and so far haven't had any issues with it. If you enjoy using a more traditional calculator for general or classroom use, you can't pass this up. Especially because the free version isn't handicapped in annoying ways like most other apps. My thanks to the developers for that! 😃 However, the layout changes w/paid ver and that sucks. Also, trig funcs have a rounding error far out.
